DETACHABLE SPOUT FOR CONTAINERS Filed Sept. 5, 1930 2 Shets-Sheet 2 A TTORNE Y5 WITNESS Patented May 17, 1932 UNITED STATES PATENT OFFICE FRANK R. STAMER, OF FLORAL PARK, NEW YORK, ASSIGNOR TO MUN'DO PRODUCTS, INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK DETACHABLE SPOUT FOR CONTAINERS Application filed September 5, 1930. Serial No. 479,835.

My invention relates to containers, and more particularly to detachable spouts for containers. such as cans for dispensing liquids. An object of the invention is to pro- 6 vide a spout of the detachable type associated with a sealing disc in such a manner that it can easily be seated in fluid-tight fashion upon the suitably formed discharge end of a container and also quickly unseatcd therefrom. It is also an object of the invention to provide a detachable spout of this kind which is reversible, so that in its inoperative position it extends from the container nozzle into the interior of the container and may be reversed and attached to the container nozzle to extend outwardly therefrom in operative position. Afurther object of the invention is to provide a spout of this character which may be easily attached to the container nozzle without manipulation of any other portion of the container. A still further object of the invention is to provide a detachable spout having a pouring lip so P as to make it possible to direct the liquid being dispensed from the container lnto a uniform and easily controllable stream.

In the accompanying drawings, in which various modifications of my invention are illustrated, Fig. 1 is a central vertical section of a container provided with a spout in accordance with my inventionj Fig. 2 is a top plan view of the container; Fig. 3 is a partly sectional elevation of the top portion of the container with the spout attached thereto in its reversed or operative position; Fig. 4 is a top plan view of the structure shown in Fig. 3 with a portion of the sealing disc broken away: Fig. 5 is a bottom plan view of the sealing cap illustrated in Fig. 1; Fig. 6 is a fragmentary sectional view of a modified form of my invention showing the spout in its inoperative position within the container: Fig. 7 is a view showing the spout of Fig. 6 in its reversed or operative position 8 and 9 illustrate a still further modified form of my invention. Fig. 8 showing the spout within the container and Fig. 9

showing the same extending outwardly therefrom; Figs. 10, 11 and 12 illustrate another embodiment of my invention in which a short spout having a pouring lip is used in connnctlon with a container in a manner similar to that of the modifications illustrated in Figs. 1 to 9; and Fig. 13 illustrates the embodiment of the invention shown in Figs. 10, 11 and 12 with the exception that a modified form of sealing cap is used so as to eliminate the necessity of inverting the nozzle into its inoperative position before placing the closure cap on the container to close the latter. I 'leferring more particularly to the drawngs, in which similar reference characters identify similar parts in the several views, the numeral 14 indicates a disc forming the top of acontainer 15 provided with a nozzle- 1 6 having bosses 17 at spaced portions of its circumference. The nozzle 16 of the contamer is secured to the disc 14 along its base in any suitable manner, for instance, by soldering. A sealing cap 18 is provided with inwardly bent flange sections 18' (Fig. 5) adapted to engage under the bosses 17 to seat the "ap m sealing position upon the nozzle 16. The central portion of the sealing cap is drawn to present a raised portion 19. An annular washer 20 may be interposed between the inner surface of the sealing cap and the top edge of the nozzle to insure a fluid-tight closure therebetween.

The container nozzle is bent downwardly and inwardly at its upper edge to provide a seat 21. for a disc 22 perforated at its center to permit the passage therethrough of the base portion of a spout 23 terminating at the base of the disc 22. The perforated disc 22 comprising an annular flange 25 so shaped as to rest upon the seat 21, and an annular body portion 26 whose external diameter is substantially equal to the internal diameter of a vertical wall 22' extending downwardly from the seat 21, so that the disc body portion 26 is capable of being wedged in fluid-tight manner within said wall. The disc 22 is so dimensioned that it engages tightly the inner periphery of the container nozzle when properly seated therein and forms a fluid-proof seal therewith, the spout being thus held rigidly within the mouth of the container to prevent displaoement thereof and breaking of such seal while the liquid inthe container is being poured out. When it is desired to close the container, the spout 23 may be grasped by the hand and given a slight jerk to disengage the disc 21 from its seat after which the spout may be inverted andi'nserted into the contain- By mounting my spout upon such disc I ob?- tain a structure which has the just-mentioned advantages ofthe tamper-proof disc, i. c. it can be easily forced into its sealing position and is of such simple construction that its cost of manufacture is small. and in addition the further advantage that when the spout is, in itsv operative position (as shown in Fig. 3), the disc can be dislodged from its seat by exerting a light push or pull on the spout, the spout then acting as a lever while when the spout is in its inoperative position (Fig. 1) the disc can be unseated by grasping the portion thereof extending above the container mouth. The sealing disc 22 can thus berepeatedly reversed without injuring the same or impairing its sealing action.

In Figs. 6 and 7 I show a modified form of ,my invention which has a certain advantage over the construction shown in Figs. 1 to 4. It will be obvious that should the container of Fig. 1 be overturned or inverted during handlin or while being transported, the liquid will ow down the spout into the space between the disc 22 and the cap 18, so that when the container is again placed in its upright position, a quantity of such liquid will become trapped between the disc 22 and the dished portion 19 of the cap 18, making it difficult for the user of the device to remove the spout from within the container and place it in its operative position shown in Fig. 3 without soiling his hands. Some of the thus trapped liquid also will flow over the top portion of the container and moisten the same,

which is generally. objectionable.

In the embodiment of the invention shown in Figs. 6 and 7, I provide the outer sealing cap 27 with a washer 28 which the extended bead portion 29 of the spout 23 is adapted to engage to form a fluid-tight seal therewith.

.By reason of such construction, any liquid the raised portion 19 of the outer sealing cap 18 is provided with an aperture 30 through which the spout 23 may be passed when inverted to extend outwardly of the container in operative position. In this form of the invention a washer 31 may be provided within the cap 18 to seal the spout. This washer is preferably wedged within the cap 18, and after the latter has been removed from the container, it may be separated therefrom with the aid of the finger inserted through the aperture 30. Upon removal of the washer, the sealing cap maybe positioned upon the container nozzle as shown in Fig. 9, the spout passing through the aperture 30 of the sealing cap. The annular washer 20 between the inner surface of the sealing cap and the upper edge of the nozzle will hold the disc 22 tightly seated within the container nozzle.

In the embodiment of the invention illustrated in Figs. 10 to 12 I employ, instead of the long spout 23, a short spout 32 provided with a pouring lip 33. The structure shown in Figs. 10 and 12 is in other respects similar to that ofFigs. 8 and 9. While the long spout 23 of F igsrl to 9 is. of particular advantage when liquid from the container is to be dispensed to a comparatively inaccessible point, it is obvious that all of the advantages of my invention may to an equal degree be obtained with a container having a short spout.

In Fig. 13 is illustrated astill further modified form of my invention in which a short spout 32 having a pouring lip 33 is used in conjunction with a sealing cap 35 having a raised portion 36 of sufficient height to house the spout 32 when the latter is in its operative position, i. e. extends above the mouth of the container. The sealing cap 35 may be provided with a washer 37 within its raised portion. 36 for sealing the spout 32. In this construction the spout is ready for use after removal of the cap 18 and washer 37 as the spout is permanently in its operative position.

' All of the above forms of my invention are characterized by the fact that a'pouring spout is provided on a tamper proof seal, so as to facilitate and greatly simplify the operation of seating the spout in position within the nozzle of the container. In my improved containers, such spout element automatically assumes a tight seating as soon as the disc withwhich it isprovided is brought into engagement with the container nozzle. I am aware of prior patents disclosing dispensing devices provided with detachable and reversible spouts and I do not claim to be the first to provide a container with such spout. My invention resides rather in the provision of a structure embodying such detachable spout in association with the abovementioned tamper proof disc seal, whereby the spout may be forced into its'operative position in a simple and expeditious manner, certain embodiments of the invention illustrating containers provided with reversible spouts wherein the supporting disc22 is so constructed that it can be firmly seated within the container nozzlein both positions of the spout.

. Variations in the'specific embodiments of my invention illustrated may be obviously made without departing from my invention. I claim: The combination of a fluid container having a nozzle provided with an inwardly and with a downwardly extending flange ad acent to its outlet end, a disc, an annular flange on said disc adapted to be seated within said downwardly extending. flange in fluid-tight manner when said disc is pressed downthe openin of said nozzle, asubstantially horizontal ange on said discadapted to rest on said inwardly extending flange, a spout so mounted on said disc as to extend into said container when said disc rests'upon said in- .ward flange in one position thereof, and to extend outwardly of said container when said disc is seated within said downwardly extending flange in the reverse position thereof, and a sealing cap for closing the outlet of said nozzle.
